To all whom it may concern:

Be it known that I, GEORGE N. WTOLF, a

citizen of the United States, residing at Anderson, in the county ofMadison and State of indiana, have invented certain new and usefulsanitary Improvements vvin :Cream- Separatore; and l do hereby declarethe tollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled inthe `art to whichitappertains to make and use the same,

My invention relates to new and useful improvements in sanitary creamseparators, and has for its object to provide .a device of this typewhich will thoroughly separate the cream from the milk by centrifugalaction.

A further object ofthe invention iS top provide suitable beaters to`agitato the milk and cream as it is emptied into the separator. And astill further object is to so construct the ports through which the milkand cream'are discharged from the separator, that said ports shall bereadily accessible vforv cleaning; and a still further object is to.provide means for regulating the size of the' ports through which themilk is discharged.

@ther objects and advantages of the invention will be hereinafterdisclosed, and

- of this application, Figure 1 is a vertical transverse sectional viewthrough the separator. Fig. 2 is a horizontal sectional view as eeen online 2 2, Fig. 1.4 Fig. 3 is a detailed perspective view of portions ot'beaters or agitators, and Fig. f1 is an elevation of the device employedfor regulating the discharge opening for the cream.

Referring to the drawings in whichreference characters designatecorresponding parts throughout. the several views, 1 indi cates the bodyof the separator, which is preferably cylindrical and provided with aclosure 2 at its lower end, said closure having a circumferential rib 3,which is exteriorly threaded and adapted to engage the threaded interiorot' :the lower end of the body 1. y

Adapted to rest on the closure 2, are beatn ers or agitators 4 and 5,said beaters being preferably arranged in pairs and secured together attheir lowerends by .means of cross arms 6 and 7, respectively, the crossseats 9, the rib 3, thereby causing said 1 beatersto rotate with thebody 1.

The u per ends of the beaters 4t and 5 are providedhvith stems 10 and11, respectively, which are adapted-to extend through a plate 12,*tl1e uper end-s of said stems being then upset to orm heads 13, and by whichmeans the plate is locked in. position on the beaters. The .centralportion of the plate 12 is prov'ded with an opening 14, throi'xgh whichthe milk passes on its way to the lower end of the' body 1, while theouter edges ot the beaters are provided with a plurality ot .curvedrecesses 15, which permit of the circulation of the milk between thebeaters and a casing 16, surrounding said beaters, the lower end of thecasing entering channels I7 formed in the upper edges of the cross arms6 and 7, while the upper end thereof extends'a distance above the upperend ot' the beaters, and is connected to a duct 1S, through which themilk is entered intothe body 1.

The upper end of the body 1 is provided with a cap 19, the lower end ofwhich is exteriorly threaded to engage threads on the interior of thebody, said cap being provided ,with ports 20, which ports are formed bycutting channels into the edge of the cap, sothat when .the cap isremoved from the body, the ports will be open their full length and bereadily accessible for cleaning.

The central portion of the capis provided with a substantially conicalopening 21, through which the duck 1S extends, the

diameter ofthe opening being greater than vthe diameter of the duct,whereby the cream when separated from the milk, will pass into saidopening and througha port 22 extending through the wall of the cap, andin order to regulate the iow of' the cream through the port 22, ,acollar 23- is introduced .into the upper end of the opening 21, andaroundV the duct 18, the lower end24 being substantially spiral, whilethe upper lend thereof is provided with a circular head 25. Said head isadapted to extend over the upper end ofthe calp ,'19, and byd'orming thecol ar of proper ength, the `flow of the cream tlirougrli the port 22may be readily regulated by rotal in;` the collar, the position lo whichthe collar is to be turned to obtain a certain llow. .beiner Araged byproviding` indicative lines 21S on the outer face of the head, acooperating zero point, (not showin) being lornied ou the cap. 'l`herotating of the collar in one i'lirectioii, in consequence o'l5 theiiuflimition ol: llie lower end thereof, gradually closes the inner endot' the port 22, while rotatingthe collar in the opposite dirci-,tionwill `gradually'increase the openiiigin tlie'port.

Any suitable form oit means may be provided vl'or preventing the leakageof the milk and cream around the duct 1S, but iii this instance, thewall o'l the opening through the collar 23 is proif'ided with aichannel27, in which is seated a gasket 28 of rubber or other expansiblcmaterial', said `gasket en- "gaging the sui-tace of the duct withsittlieient pressure to prevent leakage between the duct and'collar.

Positioned below the eap '1 $),aiid surrounding` the duct 1.8-, acorrugated cone or spreader 2S), the base 30 ot which is slightlyupwardly inclined trom its center 'so that when the milk and creamengage the base, the same will readily pass toward the outer edge oft'the cone or spreader, and in order to permit the milk and cream to passupwardly, and through their respective ports, the periphery ot thespreader or cone is provided with a plurality of ribs 31, therebyforming grooves 32. through which the vcream and niilkniay pass,`thelower end of the cone engaging a circumferential shoulder 323 toi-med byswaging inwardly parts of the wall ot' the body, said shoulderlimitingthe downward movement of the spreader. v

ln addition to the ports 2() for-the discharge ot4 the milk at the upperend of the body .1, the closure 2 may be also provided with ports Sill,as shown by dotted lines iii Fig. 1, by which construction the separatorwill be provided with a top or bottom delivery il'iir the milk, asoccasion may require'.

ln clan-ation, the milk and ci'eam are/iutrodueed into the 'duct 1.8,and enter the casing .16, and as the casingand body are rapidlyrotatiiig, will be violently agitated by the beaters 1 and 5, giving thesame a swirling movement in View of the space between the beaters andthe recesses at the edges ot the beaters adjacent to the casing. Themilk and cream then pass below the lower end ot the casing, Where thesame are" engaged and further agitatedby the cross arms 6 and 7. Theparticles of milk and cream enter the body l and are raised bycentrifugal action to the upper end of said body and as the cream islighter than the inilk, it passes to- Ward rae center of the body, whilethe milk 1 lar body, a closure for the lower end remains vadjacent tothe outer edge of the body. As the particles encounter the spreader orcone 29, they again pass into more or less eomminglcd relationship with'each other, until they enter the grooves 32, when, in lview ot' thetaper of the spreader, the cream-particles will abruptly leave the milkand pass upwardly into the opening 22, while theuiiiilk will adhere tothe walls of the body l and pass out through the ports 20.- Inassembling the several parts, the beaters are placed in position on theclosure 2, and the casing 16 is then introduced around the beaters,after which the spreader or cone 29 iasintrochiced over the upper end ofthe duct 18, and suitably seated on the shoulder 33, when the cap 19 isplaced in position and screwed into the upper end of the body and thecollar 23 introduced around the duct 18, and properly seated upon thecap.V

By this construction, it will be readily seen that all of the parts canbe separated and thoroughly cleaned, the various ports lieiiipr soconstructed as to be readily accessible tor cleaning the-same, and ifdesired, the closure 2 may be removed from the body for cleaning.

What l elaini is: 1. A cream separator, comprising' a'tubular bodyhaving aI closurelat one end, the upper 'face of which is provided witha rib having seats therein,- a plurality of beaters having interlockingcross arms at their 10W-er ends and a plate at their upperen'ds, acasiiiuiiieating with said casing, a spreader adjacent to the upper endot the body, support ing means for the spreader, a cap engaging theupper end of the body having ports therein, anda collar having means atvits lower end adapted to cooperate with one ofv said ports to increaseor decrease the discharging capacity ot said port,
